Answer:
The molecular weight of the gas mixture is 35.38 g/mol.
Explanation:
The molecular weight of the gas can be found using the following equation:
Where:
m: is the mass = 230 g
n: is the number of moles
First, we need to find the number of moles using Ideal Gas Law:
Where:
P: is the pressure = 135 psi
V: is the volume = 15 L
R: is the gas constant = 0.082 L*atm/(K*mol)
T: is the temperature = 465 °R (K = R*5/9)
Finally, the molecular weight of the gas is:
Therefore, the molecular weight of the gas mixture is 35.38 g/mol.
I hope it helps you!
Answer:
Fuel efficiency for highway = 114.08 miles/gallon
Fuel efficiency for city = 98.79 miles/gallon
Explanation:
1 gallon = 3.7854 litres
1 mile = 1.6093 km
Let's first convert the efficiency to km/gallon:
48.5 km/litre = (48.5 * 3.7854) km/gallon
48.5 km/litre = 183.5919 km/gallon (highway)
42.0 km/litre = (42.0 * 3.7854) km/gallon
42.0 km/litre = 158.9868 km/gallon (city)
Next, we convert these to miles/gallon:
183.5919 km/gallon = (183.5919 / 1.6093) miles/gallon
183.5919 km/gallon = 114.08 miles/gallon (highway)
158.9868 km/gallon = (158.9868 /1.6093) miles/gallon
158.9868 km/gallon = 98.79 miles/gallon (city)
Answer:
146494 kw
Explanation:
Given data:
Turbine inlet pressure ( p1 ) = 16 MPa
Turbine inlet temperature ( T1 ) = 560°C
condenser pressure : P3 = 8Kpa
Extracted steam at pressure ( P2 ) = 1 MPa
mass flow rate of steam ( m ) = 120 kg/s
<u>a) The net power developed </u>
= 146494 kw

The most popular nonmetallic cable for residential outdoor wiring lines is type UF cable. With a minimum of 24 inches of earth cover, UF cable can be directly buried (without conduit).
Type NM cables must be shielded by listed bushings or listed grommets that cover all metal edges if they run through factory- or site-made gaps in metal frame members. Within a wireway, splices and taps are acceptable as long as they are accessible. At that point, the conductors, including splices and taps, shall not fill the wireway to a maximum of 75% of its area. Circuit conductor sections supplying an outlet must be removed from the raceway when the outlet is abandoned, discontinued, or removed.
